QB#80 - Make bot able to determine if item is stackable

Trac Ticket #58 - Originally reported by: Korrode

Right now there is a “Stackable” entry for each item in the DB. This has to be set manually atm. If not set correctly it can make the allocated slots info output from the “status” command look confusing. (i.e. more than 36 slots allocated. 36 is maximum in EL).

Please make the bot determine if an item is stackable and set it as such.

Until that is done, if you can be bothered, remove “Stackable” column from WBI and allocated slot info from “status” command output.
